Re: "Final" Dell XPS 420 Video Card Upgrade Question(s)
You are not limited to buying Dell parts and it would be better to buy 3dr party parts. The system is most likely out of warranty so there will be nothing to worry about on that end. While Dell does use some custom setting there is nothing related to your upgrades that will be of issue. The 250 is a good card and will fit nicely in the system. Upgrading the ram to 4 or 8 gigs will also give the system a performance boost.
